The Alu-Dec 315 mm in a 10-meter roll is the largest flexible aluminium duct in our range, designed for industrial and commercial ventilation systems. This size ventilates entire halls, large greenhouses or commercial growing facilities where standard diameters fall short. Minimal air resistance, maximum volume. Cut to length and secure with a suitable clamp. Order at plantandflower.be.

Alu-Dec 315 mm flexible aluminium duct – 10 meters

The Alu-Dec 315 mm is the largest flexible aluminium duct we stock. At 10 meters long with a 315 mm bore, it is built for applications where standard sizes simply cannot keep up. Fasten it with a hose clamp rated up to 370 mm for a secure, airtight seal.

The biggest bore in our catalogue

A 315 mm duct provides more than six times the cross-sectional area of a standard 127 mm hose. That massive difference makes it suitable for climate control in large greenhouses, air distribution across commercial grow facilities spanning dozens of square meters, and industrial extraction in factory or warehouse halls. Where smaller ducts hit their ceiling, the 315 mm is just getting started.

Planning your installation

Ducting this size is bulky and far less manoeuvrable than smaller diameters. Map out the route carefully and confirm that ceilings, shafts or penetrations offer enough clearance. Tight bends are practically impossible at this diameter, so plan wide, sweeping curves. If 315 mm is more than you need, the Alu-Dec 250 mm 10-meter roll delivers strong airflow in a more compact package.

Is 315 mm ducting still flexible enough to route through a building?

Yes, but with limitations. The Alu-Dec 315 mm bends gradually and handles gentle curves well. However, sharp 90-degree turns are not feasible at this diameter. Plan straight runs with wide bends, and ensure all penetrations and shafts provide at least 35 to 40 cm of clearance.
